The process currently involves super cooling phosphorus atoms in a silicon matrix and then making the spin of the atoms "flip up and down 'in concert for a few billionths of a second,'" with magnetic fields and microwave radiation. A final product is still at least 15 years off, but this could give a glimpse into the future of supercomputing."
